I doubt that you can get it delivered the same day because what if it never shows up that day. Can you go down and pick up all of your speakers with a truck or trailer? They will let you do that if you can, but I do know that fedex freight has Saturday delivery.

Is that the normal process and if so do they schedule a delivery the same day if possible?

They called me today, scheduling an appointment today to drop them off, so you may be in luck. Who knows.

Saturday delivery would be fine, I'm just hoping it won't be pushed to next week. Friday-Sunday is a normal weekend off of work for me, so it would be nice to not have to miss any work to be home for the delivery.

That would be nice, I guess it depends on how much they have to deliver in my area, etc. I was hoping to get it setup tonight and spend all day tomorrow on calibrations and testing. Now I will just shoot for the weekend!

It seemed to me like a strange request anyway when doing it yourself is so easy.

Upon further inspection Rob the middle compartment in the older T8's are not like 2010 and above in that the older Selenium 220 compression drivers had to be sealed. It was actually Jeff's idea to have them shipped to him so he could modify if needed. I guess I just assumed they would be replaced in a "driver" upgrade. And especially since one of the drivers cones has a couple creases in it. So it wasnt a drop in replacement due to the inner design of his older T8 cabinets. I had mentioned it before, perhaps you missed it smile.gif

On another note. So the different drivers doesnt mean the crossover needs to be tweaked differently? I always thought crossovers were designed driver specific but i'm lacking much knowledge in that department.

How do they sound?
Chris

Heading home in 20 minutes and will see. Mostly I had assumed since one is slightly damaged. But I assume Jeff tested everything out fine.

Plus when I did my Xovers, every single speaker solder point on the boards came off and I spend 2 hours dinking around re-soldering broken tabs that didn't fit. Even though it may have been easy for RMK, that doesn't mean it will be for everyone that isn't comfortable doing it. If I didn't know how to solder, I would have been up poops creek!

My original T12's had the coax/cd mounted in a sealed back chamber too. I replaced the CD by unscrewing it from the back of the coaxial driver once I removed it. I did not modify the cabinet and it was a drop in replacement. Perhaps the newer CD's require a cabinet center chamber modification.

I also had some of the female mounting holes that were a bit mangled from previous owners doing something. Probably over tightened with a drill...I don't know if he had to modify the cabinet. Anyway just hooked them up and testing out some of my wife's music (Allison Krauss). It has a lot good instruments and sounds really good! I need to run Audyssey as they are playing on the JBL's calibration so I am sure they will improve. Perhaps I can do everything right the first time lol! As in I always forget to change the Submersives to the lowest PGM setting or forget a setting on my mini dsp unit.

Also, the humm is worse frown.gif I expected this. So that will be a journey of fixing...

Congrats! What is behind your front speakers?
post #16361 of 18374
What listening preset do you guys use? I always liked PLIIX with the ambient surround. But as I am flashing back and forth from that to Stereo with the JTR's the soundstage becomes soooo much wider on Stereo. Of course the Dolby preset does some central imaging magic...

I use all channel stereo or 2 channel stereo mostly and audyssey DSX when I want to activate the wides.
post #16363 of 18374
^yea, I can see myself transitioning to 2 channel Stereo. I like everything about the Dolby but the vocals are super centralized and it creates a tiny sweet spot. But they create it that way on purpose

What's the best way to clean Duratex, assuming that is the official standard finish on all JTR speakers?

And how scratch resistant is it?
post #16365 of 18374
The finish is not Duratex but it is a really similar product. To clean lightly brush/wipe using a slightly damp rag but not microfiber as it will catch on the finish, an old t-shirt works well.

The finish is fairly durable (think smooth fine textured truck bed liner) but like any finish it will scratch if enough force is put into it.

Don't use paper towels with Pledge multi surface. smile.gif Anything fuzzy or made of paper will stick.
mtg90 recommendation is as good as I have found = a warm barely damp rag.

post #16367 of 18374
I have used "sprayaway" amonia free glass cleaner and a regular towel with great results. As others have said, don't use paper towels or anything with fibers that come off as you will see them all over the finish on the JTR speakers. I learned that the hard way smile.gif

Clean the speakers? confused.gif

In their natural habitat (i.e. behind a screen wall) the point is moot. wink.gif

Yikes! Is that what is meant by speaker porn? eek.gif
post #16370 of 18374
I've found the finish on the JTR to be pretty ridiculously durable. I"ve transported my subs and speakers probably a dozen times to places, and you can't tell I've ever moved them.

One trip I had a 228 seat belted in left rear and another in the right rear passenger seat in my car. I took a corner too fast and one smacked into the other with a LOUD crack - like a gun went off. I imagine the hollow ported cabs amplified the sound - but it was LOUD! I thought oh crap - that's going to leave a mark. I pulled over and checked and you'd never even know. The mar was soo slight as to be completely indistinguishable unless I point it out. I doubt I could even find it now.

post #16371 of 18374
I agree the JTR's are durable but not compared to that Danley finish!! No wonder they ship those things with no protection other than 2 tiny (and I mean tiny) corner protectors for just the front and nothing but the cardboard box for the rest of it.

I felt like I could have taken a box knife to the finish of the Danley and would have had a hard time making a scratch.

RLO and it's offset just makes the aggressiveness of the "Dynamic" feature less prominent. Essentially, Dynamic EQ boosts the lows and also to a lesser extent, the highs. At reference, there is no boosting of anything, as you are at reference, the further you travel away from reference, the more aggressive the DynEq boosting goes. With RLO, it adjusts the "reference" level down to -5,-10,-15 therefore essentially making Dynamic EQ's boost less aggressive overall at lower listening levels. So, if you were to choose -10, and were listening at -10, there would be no effect by having dynamic EQ engaged.

Similar to what the "threshold" control does on the inuke dsp.

Here it is with the threshold turned to 0, the boost to the lows is pretty much the same no matter how loud the overall volume is.




Here it is with the threshold knob turned some, works more like dynamic eq on Audyssey. The louder you go the less the bass is boosted:






So cool, I wish the minidsp had this dynamic eq function. This is why I was looking into replacing my CV5000 with the inuke6000 dsp but I tested the CV against 2 of my 3000 dsp's and the inukes got overworked and stopped putting out sound for about 10 seconds while the fans cranked up so high and loud it scared me so unfortunately I can't switch to the 6000 dsp. The CV never has any issues with getting louder or shutting off the audio. The dual inukes were capable of 0.5 more db's that the CV so they kept up.... until they muted and started roaring like crazy. The amps are in another room and it was still crazy loud through the wall.
post #16374 of 18374
carp,

How often do you go +9dB over reference for long bass marathons? (clip the CV-5000?)

Since the single iNuke 6000 would go to the same volume as the CV, and has a feature set you will constantly use (do a fan mod to quiet it down and enjoy it) - I personally think it'd be worth the trade. Dynamic EQ would be used much more than max volume listening.

If not a 6,000, then wait for a 12,000, which wouldn't be running an impedance it is uncomfortable with and should behave better at the limits.

(12,000 inuke is specified to run 2ohm load -- 6,000 is not - and you were running a 2.67 ohm load with the six SI subs attached to a 6000 - so the iNuke's were taxed beyond their stated limit.)

That 9 over reference (actually 19 over reference since the sub trim was at 0 which is 10 db's hot for my setup) was with the song Bass I Love You, for music I've found the subs can handle louder MV levels that with movies.

So with the 6 subs up front and the back 2 subs turned off:

+19 clipped with Bass I Love you with the inuke. (+9 on MV 10 hot on sub trim on avr)

+3.5 clipped with WOW Pod scene with inuke ( -6.5 on MV 10 hot on sub trim avr)

+ 6.5 clipped with Art of Flight with inuke ( -3.0 on MV with 10 hot on sub trim avr)




How often to I crank it this much? Very, very rarely when alone but quite often on demo's and I've had those levels on the CV for WAY longer than I did on the inukes many, many times for demo's. The CV doesn't even seem to care if I clip it do death. I'll I get is a slight chirping sound from the drivers (you've heard this) and eventually a breaker trip during clip city.

I think it would drive me crazy to know that I switched amps and am now more limited. So, either waiting for the 12000 or sometime getting 2 6000's may be in my future.

To give you an example, you remember the night we had a bunch of guys over and the beer/drinks were flowing and I cleaned my drink spill on the carpet with bleach? redface.gifbiggrin.gif
I clearly remember on Art of Flight turning the MV as loud as it would go (+12) and the subs WAYYYY hot - hotter than 10 dbs for sure. Luke went runnning into the laudry room with his hands over his ears, haha.

That had to have been clipping the ever loving crap out of the CV and it just didn't care. We didn't even trip the breaker on that.


I think I'm one of those guys that needs to be able to have gear that you can turn it up as loud as it can go and nothing bad happens. smile.gif

To be fair, you and Popalock likely eat BASS powerbars for breakfast. My "overkill" is your starting point. The bass in your room laughs at me...it taunts people like me...makes us feel like little girlz smile.gif Someday you need to have GTG at your pad. I probably would leave in tears and assume the fetal position in the corner.

I know there are several JTR owners that have the XMC 1 on order. Just saw this posted on another thread. Looks pretty sweet....eager to hear back first hand user reports.
